Experimental Design (Public)
|
Before
The study is a two-arm cross-randomized control trial. It will involve four groups: the first treatment group will receive an active intervention focused on children's health and parenting modules twice a week (Group A). The second treatment group will receive modules on improving parental mental health practices once a week (Group B). A third group (Group AB) will receive both sets of modules, totaling three sessions per week. The control group will receive standard government-approved documents on nutrition and health practices once a week, along with healthy recipes (Business as Usual). Surveys will be conducted at three points: baseline (week 1), midpoint (week 7), and endline (week 12) for all intervention groups.

After
The study is a 2x2 randomized control trial. All arms, including the control group, will receive standard government-approved documents on nutrition and health practices once a week, along with healthy recipes (Business as Usual). Treatment Group A (Nutrition) will receive a narrative and gamified chatbot focused on healthy nutrition practices recommended by the Peruvian Ministry of Health. This will come in the form of WhatsApp messages once a week for 12 weeks. Treatment Group B (Psychosocial) will receive psychologically wise interventions centered in problem solving and affirmation as well as cognitive behavioral therapy-based modules once a week. Treatment Group AB will receive both sets of modules, totaling three sessions per week. Surveys will be conducted at three points: baseline (week 1), midpoint (week 7), and endline (week 12) for all intervention groups.
